TECHNICAL FIELD

This invention relates to terpenes and uses thereof. In particular, the invention relates to serrulatane diterpenes and to the use of such compounds in the treatment of diseases and disorders such as cancer.

Throughout this application, various publications are referred to by first author and year of publication. Full citations for these publications, in the order they appear in the application, are presented in a References section immediately before the claims.

BACKGROUND OF THE INVENTION

Plant secondary metabolites have been a major source of medicinal substances providing lead compounds for drug discovery and development.

Plants produce resins and exudates containing secondary metabolites to protect young flower and leaf buds against bacteria and fungi, and damage from sunlight. Accordingly, compounds from plant resins and exudates frequently possess antimicrobial and antioxidant/free radical scavenging activities. Worker honey bees (Apis mellifera) collect plant resins/exudates of young shoots and buds from certain trees and shrubs. The resulting mixture is called propolis, or so called bee glue. Propolis is a complex resinous substance and a rich source of bioactive substances. It is used by the bees to mix with wax to seal cracks and holes in their hives and as a disinfectant to protect against microbial infections. The medicinal properties of propolis have been exploited by man since Ancient civilizations.

Currently, propolis is extensively available as a natural health product, and is widely used in cosmetics. However, its modern use in medicine is limited, largely due to the wide variations in chemical compositions arising from honey bees collecting from different or a mixture of plant sources. The composition of propolis is dependent upon the surrounding flora to which the bees have access, and as such, differences in flora may result in differences in propolis compositions. For example, it is known that flavonoids are the major pharmacologically active compounds in European propolis, polyprenylated benzophenones are the main substances in Cuban and Venuzuelan propolis, and prenylated cinnamic acid derivatives are predominant in Brazilian propolis.

Recognition of the botanical origin of the propolis produced by honey bees enables beehives to be placed in favourable locations such that propolis from a single botanical source may be produced to enable manufacture of medicines of high quality and efficacy.

The medicinal uniqueness of propolis is determined by the selective collecting ability of honey bees, as they can recognise natural materials that are relatively non-polar and have antibiotic properties. As reported, the common source of propolis is leaf and flower bud exudates, which are of high antibiotic character in order to protect the delicate growing of plant tissue from attack by microorganisms. It has also been reported that honey bees collect exudates from wounded or diseased plant tissues. Such sources are potentially rich in antibiotic substances produced by plants in response to wounding or attack from insects, microorganisms and viruses.

Medicinal properties of a propolis are associated with the biological activities of the individual plant resins/exudates. It is not clear from previous studies whether the bees simply collect a plant material that is known as propolis, or if there is metabolic modification or addition from the bees. However, there does not appear to be evidence of significant amounts of material added from honey bees, or strong evidence for metabolic transformation. Thus, a better understanding is required regarding the composition of propolis in specific geographical locations to be able to utilize it to its full benefit in the development of new agents in the treatment of diseases and disorders such as cancer.

SUMMARY OF THE INVENTION

In work leading up to the present invention a survey of propolis samples isolated from Kangaroo Island (South Australia) was conducted. Surprisingly, the Inventors found that unlike other propolis which commonly contains flavonoids as active constituents, Kangaroo Island propolis from the Myoporum genus of plants, in particular Myoporum insulare, contains serrulatane diterpenes. Thus, the present invention relates to compounds isolated from the resins/exudates of leaves and leaf buds of Myoporum insulare, propolis sourced from the same plant and uses thereof.

Myoporum insulare species is a shrub occurring on ridges and coastal cliffs in Australia. Common names include boobialla, native juniper and, in Western Australia, blueberry tree. Myoporum is a genus of approximately 30 species, of which sixteen are found in Australia. Myoporum insulare species has a variable growth habitat and may be a dense or an open shrub or a small tree up to 6 metres. The leaves are lance-shaped to elliptical, 30-100 mm long by 10-20 mm wide with glossy green colour. The flowers occur in groups of up to 8 in the leaf axils in late spring and summer and are usually white or occasionally pale pink.

The Inventors have isolated five major compounds, namely compounds 1 to 5, from propolis obtained from Myoporum insulare. Compounds 1 to 5 are shown in Table 1. The conventional numbering for serrulatane compounds is shown with respect to Compound 1. In general, serrulatane diterpenes have the (1R,4S)-configuration (Ghisalberti, 1994).

Compound 1 gives a derivative, Compound 6, on oxidation. Further in regard to derivatization, the compounds can also be acylated, alkylated, alkenylated or benzoylated through the free hydroxyl groups. For example, compounds 1 and 2 can be acetylated to give derivatives 7 and 8 while benzoylation can give derivatives 9 and 10.

Representative compounds were evaluated for pharmacological activity and were found to be useful in modulating a number of diseases or disorders. For example, the compounds were found to inhibit cancer cell proliferation and showed moderate to strong inhibition of various targets associated with cancer pathology. This indicates that the serrulatane diterpene compounds of the present disclosure may be useful as therapeutic agents e.g. for the treatment of cancer. The compounds were also found to effectively inhibit inflammatory activity and modulate immune response, showing moderate to strong inhibition of COX1 and COX2, the release of proinflammatory cytokines, lipoxygenase and the nuclear transcription factor NF-κB. Therefore, the serrulatane diterpenes described herein provide a potentially attractive lead for pharmaceutical research and development and as biological tools for further understanding the pathophysiology of diseases and disorders such as cancer, and diseases and disorders associated with inflammation, such as skin inflammatory conditions.

As used herein, the term “solvate” refers to a complex of variable stoichiometry formed by a solute (in this disclosure, a compound of formula (I) to (Ii) or a salt or physiologically functional derivative thereof) and a solvent. Such solvents for the purpose of the disclosure may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, methanol, ethanol and acetic acid. In particular the solvent used is a pharmaceutically acceptable solvent. Examples of suitable pharmaceutically acceptable solvents include, without limitation, water, ethanol, acetic acid, glycerol, liquid polyethylene glycols and mixtures thereof. A particular solvent is water.

Administration of compounds of the formula (I) to (Ii) may be in the form of a “prodrug”.

A prodrug is an inactive form of a compound which is transformed in vivo to the active form. Suitable prodrugs include esters, phosphonate esters etc, of the active form of the compound.

It should be understood that in addition to the ingredients particularly mentioned above, the formulations may include other agents conventional in the art having regard to the type of formulation in question.

The compounds of the present disclosure may be suitable for the treatment of diseases in a human or animal subject. In one example, the subject is a mammal including a human, horse, dog, cat, sheep, cow, or primate. In another example, the subject is a human. In a further example, the subject is not a human. The terms “subject” and “patient” are used interchangeably herein.

As used herein, the term “effective amount” means that amount of a drug or pharmaceutical agent that will elicit the biological or medical response of a tissue, system, animal or human that is being sought, for instance, by a researcher or clinician.

Furthermore, the term “therapeutically effective amount” means any amount which, as compared to a corresponding subject who has not received such amount, results in improved treatment, healing or amelioration of a disease, disorder, or side effect, or a decrease in the rate of advancement of a disease or disorder. The term also includes within its scope amounts effective to enhance normal physiological function. The term also includes within its scope amounts effective to prevent a disease, disorder, or side effect.

As used herein the term “treatment” refers to defending against or inhibiting a symptom, treating a symptom, delaying the appearance of a symptom, reducing the severity of the development of a symptom, and/or reducing the number or type of symptoms suffered by an individual, as compared to not administering a pharmaceutical composition comprising a compound of the invention. The term also includes within its scope prevention of a disease, disorder, or side effect. The term “treatment” encompasses use in a palliative setting

The antitumor effect of the compounds of the present disclosure may be applied as a sole therapy or as a combination therapy i.e. where two or more serrulatane diterpenoids may be administered in combination. Therapy may also involve administration of a mixture of two or more serrulatane diterpenoids. Therapy may involve, in addition, administration of one or more other substances and/or treatments. Such conjoint treatment may be achieved by way of the simultaneous, sequential or separate administration of the individual components of the treatment. In the field of medical oncology it is normal practice to use a combination of different forms of treatment to treat each patient with cancer such as a combination of surgery, radiotherapy and/or chemotherapy. In particular, it is known that irradiation or treatment with antiangiogenic and/or vascular permeability reducing agents can enhance the amount of hypoxic tissue within a tumour. Therefore the effectiveness of the compounds of the present invention may be improved by conjoint treatment with radiotherapy and/or with an antiangiogenic agent.

The individual components of such combinations can be administered separately at different times during the course of therapy or concurrently in divided or single combination forms. The present disclosure is therefore to be understood as embracing all such regimes of simultaneous or alternating treatment and the term “administering” is to be interpreted accordingly. It will be understood that the scope of combinations of the compounds of this invention with other anti-neoplastic agents includes in principle any combination with any pharmaceutical composition useful for treating cancer.

When combined in the same formulation it will be appreciated that the two compounds must be stable and compatible with each other and the other components of the formulation and may be formulated for administration. When formulated separately they may be provided in any convenient formulation, conveniently in such a manner as are known for such compounds in the art.

Pharmaceutical compositions of the present disclosure may be formulated for administration by any appropriate route, for example by the oral (including buccal or sublingual), rectal, nasal, topical (including buccal, sublingual or transdermal), vaginal or parenteral (including subcutaneous, intramuscular, intravenous or intradermal) route. Therefore, the pharmaceutical compositions of the invention may be formulated, for example, as tablets, capsules, powders, granules, lozenges, creams or liquid preparations, such as oral or sterile parenteral solutions or suspensions. Such pharmaceutical formulations may be prepared by any method known in the art of pharmacy, for example by bringing into association the active ingredient with the carrier(s) or excipient(s). Such pharmaceutical formulations may be prepared as enterically coated granules, tablets or capsules suitable for oral administration and delayed release formulations.

When a compound is used in combination with a second therapeutic agent active against the same disease, the dose of each compound may differ from that when the compound is used alone. Appropriate doses will be readily appreciated by those skilled in the art.

Also disclosed herein is use of a compound of Formula (I),

EXAMPLES

In order to better understand the nature of the invention a number of examples will now be described as follows:

Experimental

Materials

Honey bees observed collecting from the boobialla trees and shrubs (Myoporum insulare) were captured in plastic tubes, capped and frozen. Sections of the bee hind legs holding propolis were cut and pooled. Plant samples were obtained and dried at 40° C. in a ventilated oven (Thermoline, NSW Australia) a few days to provide voucher specimens for identification by botanist, A/Prof Murray Henwood, John Ray Herbarium, University of Sydney, Sydney, Australia, and registered as Myoporum insulare voucher number Duke-131202-01. Resin extracted from plant samples was stored at −20° C. until analysis or further processing.

Propolis was obtained from apiary sites with from 1 to 10 colonies of European honey bee (Apis mellifera ligustica) in standard 10-frame box hives, each fixed with a propolis mat under the hive cover lid. The propolis samples were collected and provided by a few beekeepers in eight apiary sites located in different parts of Kangaroo Island, South Australia. These sites were located in the vicinity of Hanson Bay, Vivonne Bay, Flour Cask Bay, Island Beach, Kingscote, Brownlow, Rainy Creek and Eleanor River. These locations are known to be a habitat for the plant Myoporum insulare on Kangaroo Island. This provided 23 propolis samples which, based on TLC analysis and ¹H NMR techniques, were estimated to be at least 90% sourced from M. insulare. The samples were stored at −20° C. until further analysis and processing.

Thin layer chromatography sheets precoated with silica gel 60 F₂₅₄ and silica gel 60H for normal-phase short-column vacuum chromatography (NPSCVC) were purchased from Merck. TLC plates were visualized with a UVGL-58 mineral-light lamp, Multiband UV-2544/366.

All the chemicals used in the isolation and synthesis, including deuterated NMR solvents such as d-chloroform, d₄-methanol and d₆-dimethyl sulfoxide were purchased from Novachem Pty Ltd (Collingwood, Vic, Australia). Solvents including hexane, dichloromethane, ethyl acetate, isopropanol, ethanol, methanol, and acetic acid were of analytical grade and purchased from Chem Supply, Gillman, SA, Australia.

General Methods

Rotavapor model R-114 rotary evaporator with a water bath temperature ranging between 40-60° C. was used to evaporate the solvent fraction. Vacuum pump V-700 or Vacuubrand MD 4C NT diaphragm pump (Vacuubrand GMBH, Wertheim, Germany) with vacuum controller V-800 or V-850 is used. Final drying is carried out by a Napco 5831 vacuum oven (NAPCO, Salt Lake City, USA) using a DirectTorr vacuum pump (Sargent-Welch, Buffalo, USA).

Isocratic analytical HPLC was performed on a Shimadzu UFLC, LC-20AD pump, SIL-20A HT autosampler, with a Hewlett-Packard Column, NUCLEOSIL 100 C₁₈, 5 μm, 4 mm×125 mm, injection volume 20 μl, eluted at 1 ml/min and detected at 230 nm with a UV-Vis detector (Shimadzu SPD-20A). The column was eluted with methanol-water-acetic acid (65:34.8:0.2).

Gradient analytical HPLC was performed on a Shimadzu Nexera X2 LC-30AD system, SIL-30 autosampler, with a Hewlett-Packard Column, NUCLEOSIL 100 C₁₈, 5 μm, 4 mm×125 mm, injection volume 10 μl, eluted at 1 ml/min and detected at 320 nm with a SPD-M30A UV-Vis diode array detector. The column was eluted with a gradient system made up of methanol (phase A), and methanol:water:acetic acid (40:59.8:0.2) (phase B). A solvent gradient was applied as follows: 0-2 min: 32-50% A, 2-9 min: 50-90% A, 9-12 min: 90-100% A, 12-14 min, 100% A, and finally 14-15 min: 100-32% A, maintained over 5 min.

¹H and ¹³C Nuclear magnetic resonance (NMR) analyses were carried out on Varian 400 MHz System with a SMS autosampler (Palo Alto, Calif., USA). Chemical shifts (5) of peaks in NMR spectra are reported in parts per million (ppm) and are referenced to tetramethylsilane (Si(CH₃)₄, TMS). ¹H NMR data is reported as chemical shift (5), relative integral, multiplicity (abbreviations: s=singlet, d=doublet, I=triplet, id=triplet of doublets, q=quartet, dd=doublet of doublets, ddd=doublet of doublet of doublets, bs=broad singlet, hi=broad triplet), coupling constant (Jin Hz) and assignment. ¹³C NMR data is reported as chemical shift (5) and assignment.

For low resolution ESI-MS, the samples were analyzed by Finnigan Polaris Ion Trap MS/MS system (Finnigan Corporation, San Jose, USA) using an Xcalibur 1.2 data system, in Electrospray Ionization (ESI) negative and positive modes using infusion technique.

High resolution ESI-MS were measured on a Bruker Daltonics Apex Ultra Fourier Transform Ion Cyclotron Resonance 7 Tesla Mass Spectrometer, mass spectrometry unit, School of Chemistry, The University of Sydney.

Determination of the ¹H-NMR Chemical Profiles of the Plant and Propolis Specimens

Young leaf shoots (25 g), bee hind leg (0.01 g) and beehive propolis (1.0 g) were extracted with dichloromethane at room temperature for 15 min. The extracts were filtered, dried under reduced pressure and analyzed by ¹H-NMR and HPLC. Samples were found to contain serrulatane diterpenes. Propolis and plant samples were subsequently selected for isolation of the components.

Preparation of Myoporum insulare Resin Extract

Fresh young leaves and young shoot tips were harvested from several Myoporum insulare trees. The leaves were stored in plastic bags on ice until processing within 5 days. To extract the external resin/exudate the leaves and shoot tips (4 Kg) were mixed with dichloromethane (4 litres) and after 1 hour standing the dichloromethane extract was filtered and the dichloromethane was removed from the filtrate by evaporation under reduced pressure using a rotary evaporator to give a brown partially solid dried resin (12.5 g, yield 0.31%).

Isolation and Identification of Serrulatane Diterpenes from Myoporum insulare Propolis from Kangaroo Island.

General Method

Propolis (100 g) was extracted with dichloromethane at room temperature with stirring for 1 hr. The extract was subjected to purification using normal-phase short column vacuum chromatography (NPSCVC). A step-wise gradient of mobile phase (2×100 mL) consisting of dichloromethane (DCM) and ethyl acetate (EtOAc) at 0, 1, 2, 4, 8, 10, 15, 20, 50 and 100% was employed to elute the components which were analysed by TLC and NMR. Further purification of the compounds, if required, was subsequently carried out on the same NPSCVC with different mobile phases consisting of either hexane and EtOAc or hexane and isopropanol. Structures and identity of these purified compounds were characterized by ¹H- and ¹³C-NMR and mass spectrometry including high resolution mass spectrometry. Detailed structural analyses of the isolated compound were also carried out when needed by 2D-NMR using Gradient Heteronuclear Multiple Bond Coherence (GHMBC). The major serrulatane diterpenoid was determined to be 7,8,18-trihydroxyserrulat-14-ene (1).

The conditions used in the assays including: enzymes, source of enzymes, substrate, substrate concentration, ligand, ligand concentration, tracer, incubation, detection method, and reference compound and concentration are detailed in Table 3. Appropriate literature references are also provided. The AlphaScreen detection method refers to an Amplified Luminescent Proximity Homogeneous Assay used to study biomolecular interactions (see Ullman el al. 1994). LANCE and LanthaScreen assays are based on the principle of time-resolved fluorescence energy transfer (TR-FRET) and are described, for example, in Ma et al. 2008.

The IC₅₀ values (concentration causing a half-maximal inhibition of control specific activity) were determined by non-linear regression analysis of the inhibition/concentration-response curves generated with mean replicate values using Hill equation curve fitting. Inhibition/concentration-response curve concentrations were 30, 3, 0.3, 0.03 and 0.003 μM.

Results: Epigenetic Targets, Diseases and Cancer

Epigenetic modifications can have a role in the development of a variety of diseases. Epigenetic regulation involves hierarchical covalent modification of DNA and proteins that package such as histones. DNA is regulated by methylation and demethylation on the cytosine residues. DNA methylation is mediated by members of the DNA-methyl transferase family (DNMT1, DNMT3A and DNMT3B) whereas demethylation is mediated by the family ten-eleven translocation (TET1-3). Besides methylation and demethylation, histone is also regulated by acetylation and deacetylation. The key proteins that mediate epigenetic signaling though acetylation and methylation of histones comprise histone acetyltransferases (HATs), histone deacetylases (HDMs), protein methyltransferases (PMTs) including lysine methyltransferases (KMTs) protein arginine methyltransferases (PRMTs), and bromodomain-containing proteins and proteins that bind to methylated histones (Arrowsmith et al., 2012; Plass et al., 2013; Tough et al., 2014; Biggar and Li, 2015).

Bromodomain Containing Proteins

Compound 1 showed significant inhibitory activity towards many of the bromodomain containing proteins (Table 10), in particular ASH1L, CECR2, EP300, KAT2A, PHIP(2), SP140, SMARCA2, TAF1(2), ATAD2A, BRD2(1), BRD4(2) and CREBBP. Compound 2 only showed significant activity towards BRD2(1). Recent studies have implicated bromodomain (BRD) containing proteins in a wide range of human diseases, including cancer (Taverna et al., 2007; Prinjha et al., 2012; Biggar and Li, 2015). The most investigated member of BRD containing proteins (BCPs) as drug targets is the BET family proteins. Currently, there are several BET inhibitors in various stages of clinical trials including RVX-208, I-BET 762, OTX 015, CPI-0610 and TEN-010 (see Table 14 in Tough et al., 2014).

In addition, JQ1 and I-BET have been shown to interact with NF-κB and induce apoptosis in drug resistant leukemia (Ciceri et al., 2014). NF-κB plays a central role inflammation and unresolved inflammation is involved in many disease states including cancer.

Several bromodomain containing proteins, including ASH1L, ATAD2A/B, BAZ2A/B, CECR2, EP300, KAT2A, PHIP(2), PB1, SMARCA2/4, BRD2/4 and CREBBP, have been shown to be up-regulated in many types of cancers (Tough et al., 2014; Fu et al, 2015). Hence, BRDs are therefore therapeutic targets for cancer. BRD-containing domains have been linked to the development of a number of extremely aggressive tumours containing BRD4-NUT and BRD3-NUT. CREBBP mutations have been identified in relapsed acute lymphoblastic leukaemia and are very common in diffuse large B-cell lymphoma and follicular lymphoma, Hodgkin's lymphoma. CREBBP and the related HAT are highly expressed in advanced prostate cancer and expression levels have been linked with patient survival. ATAD2 is over expressed in more than 70% of breast tumours and higher protein levels correlate with poor overall survival and disease recurrence (Ciro et al., 2009). ATAD2B is highly expressed in glioblastoma and oligodendroglioma as well as breast carcinoma (Krakstad et al., 2015). BRD4 is linked to development of cervical cancer (Weidner-Glunde et al.; 2010).

Compound 1 showed good inhibitory activity against domain PHD (plant homology domain) containing domain proteins SP140, TRIM 33, UHRF1 (108-286)).

Methyltransferases

Compound 1 was a strong inhibitor of the lysine methyltransferase enzyme G9a whereas compounds 2 and 3 were weaker (Table 10). G9a is a multipotent regulator of gene expression which has been shown to be over expressed in many different types of cancers (See reviews for details: Shankar et al., 2013; Casciello et al., 2015). Compounds 1 to 3 strongly inhibited the activity of PRMT4 and moderately inhibited the activity of PRMT6. Dysregulated PRMT expression and activity have been observed in a variety of cancers and PRMT1-5 and 7 have been shown to be overexpressed or otherwise contribute to tumorigenesis whereas PRMT8, and 9 have not been implicated in oncogenesis (Fuhrmann et al., 2015). PRMT4 (CARM1) is necessary for NFκB target gene expression. Further study showed a link between PRMT4 and p300 acetyltransferase activity in NFκB recruitment and gene activation.

Demethylases

Compound 1 showed significant inhibitory activity towards many of the lysine demethylase enzymes (Table 10), in particular JARID1A, JARID1B, JMJD1A, JMJD2B, JMJD2E, JMJD3 and UTX. Aberrant expression and mutations of lysine demethylases have been linked to various cancers (Hojfeldt et al., 2013; Tough et al., 2014). Mutation of lysine demethylases including FBXL10, JMJD2A, JMJDB, JMJD2C, JARID1B and PHF2 have been shown to be overexpressed in breast, colorectal, lung, prostrate, bladder and other tumours; the functional significance of JMJD2C overexpression is further suggested by the presence of the JMJD2C gene within an amplified region of a chromosome in multiple cancers (Xiang et al., 2007; Couvelard el al., 2008; Roesch et al., 2010; He et al., 2011a; Berry and Janknecht, 2013; Kogure et al., 2013; Tzatsos et al., 2013).

Histone Acetyltransferases

The serrulatanes diterpenes showed significant inhibitory activity on histone acetyltransferases CREBBP and MYST4 (Table 10). Misregulation of histone acetyltransferase activity has been linked to many different pathogenic states including cancers, neurodegenerative disorders, and metabolic, respiratory, inflammatory and cardiovascular diseases (Adcock and Lee, 2006; Avvakumov and Cote, 2007; Grabiec et al., 2008; Ghizzo et al., 2011, Iyer et al., 2011; Pirooznia and Elefant, 2013).

Nuclear factor kappa B (NF-κB) was first discovered as a factor in the nucleus of B lymphocytes that binds to the enhancer of kappa light chain of immunoglobulin and is also a lymphoid specific (Sen and Baltimore, 1986). The NF-κB family includes RelA/p65, NF-κB1 p50/p105, NF-κB2 p52/p100, C-Rel and RelB. These proteins contain an N-terminal Rel homology domain (RFID) that is responsible for binding to DNA and other proteins and harbour a nuclear leading sequence (NLS). NF-κB proteins function as a dimeric transcription factor that regulates the expression of genes influencing a broad range of biological processes including innate and adaptive immunity, inflammation, stress responses, B-cell development and lymphoid organogenesis (Pantano et al., 2006; Brigelius-Fohê and Fohê 2011; Ghosh et al., 2012; Akdis et al., 2017).

NF-κB has been shown to have diverse and complex roles in cancer and immune modulation (Perkins, 2012; Sethi et al., 2012; Parri and Chiarugi, 2013; D'Ignazio el al., 2015). Based on significant inhibitory activity against NF-κB (IC₅₀ 0.69 μM) and cytokines (IC₅₀ 6.6, 8.8, 4.3, 8.9 μM, for IL1β, IL-6, IL10, TNFα respectively, Compound 1 can potentially influence the expression of the aforementioned biological processes as well as modulation of immune responses. In support for these results, Eurofins Oncopanel Genomic analysis showed Compound 1 clustered near to ABT-199, a BH3 domain inhibitor of BCL-2. ABT-199 blocked anti-apoptotic of BCL-2 leading to programmed cell death. In addition to antitumor effect of BCL-2 therapeutics, the BH3 mimetics have been proposed in the context of immune modulation (Ludwig et al., 2016). Taken together, Compound 1 could target cancer cell death as well as immune modulation. FIG. 10 shows transcription response and binding against NF-κB for Compound 1.

In Vitro Cell Viability Assay of Serrulatane Terpenes

Four serrulatane diterpenes, namely compounds 1 to 4, and Myoporum insulare resin were evaluated for in vitro inhibition of cell growth in 43 cancer cell lines and one normal cell line as shown in Table 19. The assay is a 72 hour (three day) assay.

Methodology of the In Vitro Cell Viability Assay

Cell viability assays were carried out by Eurofins PanLab (Taiwan). The assays are based on the established principle that cell viability (survival) can be evaluated by measuring the intracellular levels of adenosine triphosphate (ATP) by bioluminescence in metabolically active cells (Xia, M et al. 2008). Assays are carried out by seeding cells in two plates (To and T₇₂). At time “zero” cell plate (To) is harvested, treated, and incubated for 72h (three days) when the T₇₂ plate will be harvested. The intracellular levels of ATP are measured and represent the amount of viable cells.

Cell viability assay results for compounds 1 to 4 and Myoporum insulare resin/exudate extract towards 43 cancer cell lines and 1 normal cell line are shown in Table 18.

No significant effect was observed towards HUVEC endothelium cells (normal cell line).

OncoPanel Cell Proliferation Assay

The OncoPanel cell proliferation assay measures the proliferation response of cancer cell lines to drug treatments through high-content fluorescence imaging or bioluminescence. Whereas the cell viability assay described above is a three-day assay, the OncoPanel assay is a 10-day assay.

Experimental Procedure

Cells were grown in RPMI 1640, 10% FBS, 2 mM L-alanyl-L-glutamine, 1 mM Na pyruvate or a special medium. Cells were seeded into 384-well plates and incubated in a humidified atmosphere of 5% CO₂ at 37° C. Compounds were added the day following cell seeding. At the same time, a time zero untreated cell plate was generated. After a 10-day incubation period, cells were fixed and stained to allow fluorescence imaging of nuclei. At 7 days post-seeding, the growth media were replaced and the plates were re-dosed with the test compound.

Compounds were serially diluted in half-log steps from the highest test concentration specified in the above table, and assayed over 10 concentrations with a maximum assay concentration of 0.1% DMSO. Automated fluorescence microscopy was carried out using a Molecular Devices ImageXpress Micro XL high-content imager, and images were collected with a 4× objective. 16-bit TIFF images were acquired and analyzed with MetaXpress 5.1.0.41 software.

Data Analysis

Cell proliferation was measured by the fluorescence intensity of an incorporated nuclear dye. The output is referred to as the relative cell count, where the measured nuclear intensity is transformed to percent of control (POC) using the following formula:

${P\; O\; C} = {\frac{I_{x}}{I_{0}} \times 100}$

Where I_(x) is the nuclear intensity at concentration x, and I₀ is the average nuclear intensity of the untreated vehicle wells.

Cellular response parameters were calculated using nonlinear regression to a sigmoidal single-site dose response model:

$y = {A + \frac{B - A}{1 + \left( {C/x} \right)^{D}}}$

Where y is a response measured at concentration x, A and B are the lower and upper limits of the response, C is the concentration at the response midpoint (EC₅₀), and D is the Hill Slope (Fallahi-Sichani, M., S. et al. 2013).

Time zero non-treated plates were used to determine the number of doublings during the assay period, using the formula:

${Doublings} = {\log_{2}\left( \frac{N}{N_{T0}} \right)}$

Where N is the cell number in untreated wells at the assay end point and NTO is the cell number at the time of compound addition.

Cell count IC₅₀ is the test compound concentration at 50% of maximal possible response. EC₅₀ is the test compound concentration at the curve inflection point or half the effective response (parameter C of the fitted curve solution). GI₅₀ is the concentration needed to reduce the observed growth by half (midway between the curve maximum and the time zero value). Activity area is an estimate of the integrated area above the curve (Barretina, J. G. et al. 2012). Activity area values range from 0-10, where a value of zero indicates no inhibition of proliferation at all concentrations, and a value of 10 indicates complete inhibition of proliferation at all concentrations. In rare instances, values <0 or >10 may be observed. In these instances, values <0 should be considered as equivalent to 0, whereas values >10 should be considered equivalent to 10.

Curve-fitting, calculations, and report generation were performed using a custom data reduction engine and MathIQ based software (AIM).

The OncoPanel cell proliferation results (OncoPanel, Eurofins PanLab, USA, across 280 human cancer cell lines) for compounds 1, 2 and 4 are shown below in Table 19. Tables 21 to 28 show representative proliferation response data (Table 21: MDA-MB-415; Table 22: RKO-AS45-1; Table 23: SW480; Table 24: 639-V; Table 25: Hs 729; Table 26: Hs 852.T; Table 27: HCT-8; Table 28: IM-9) and the cell proliferation results for Myoporum insulare resin are shown below in Table 29.

For Compound 1, a broad spectrum of activity was observed over the 280 cell types with very potent to strong (GI₅₀=0.006 to 2.98 μM) activity towards 174 cell lines. Very potent activity was observed towards SK-NEP-1 kidney (GI₅₀=0.00618 μM) and J-RT3-T3-5 leukemia (GI₅₀=0.0101 μM) cell lines. Moderately potent activity was observed (GI50=0.11 μM) towards KG-1 leukemia cell line. Moderately potent activity (GI50=0.4 to 1.0 μM) was observed towards the following cell lines: 2 breast cell lines KPL-1, MDA-MB-453; 3 myeloma cell lines IM-9, RPMI8226, SKO-007; 3 melanoma cell lines A7, COLO829, RPMI-7951; 7 soft tissue cell lines HOS (osteosarcoma), KHOS-240S (osteosarcoma), SW1353 (osteosarcoma), A204 (sarcoma), HT-1080 (sarcoma), RD (sarcoma), SW 872 (sarcoma); 2 small cell lung carcinoma cell lines DMS53, SHP-77; and also Colo 201 (colon); FaDu (head and neck), 769-P (kidney), HepG2 (liver), and AGS (stomach). Strong activity (GI₅₀=1 to 2.98 μM) was shown towards 149 cell lines: 16 melanoma; 15 lymphoma; 9 female genitourinary; 14 soft tissue (sarcoma); 16 colon; 12 leukemia; 8 non-small cell lung carcinoma; 8 pancreas; 9 breast; 10 CNS; 8 bladder; 5 kidney; 4 head and neck, 4 endocrine, 1 myeloma, 3 liver, 2 small cell lung carcinoma, 2 prostrate, 2 stomach and 1 testis.

For Compound 2, a narrow spectrum of activity was observed over the 280 cell types with potent to strong (GI₅₀=0.06 to 2.96 μM) activity towards 10 cell lines. Potent activity was observed towards SK-NEP-1 kidney (GI₅₀=0.0606 μM) Strong activity (GI₅₀=1 to 2.96 μM) was observed towards the following cell lines: 5 leukemia cell lines J-RT3-T3-5, Jurkat, MOLT-3, NALM-6, TF-1; 2 myeloma cell lines RPMI8226, SKO-007; 1 soft tissue cell line RD (sarcoma). For Compound 2 activities towards Jurkat, MOLT-3, NALM-6, TF-1 (leukemia) and SKO-007 (myeloma) were similar in magnitude to Compound 1.

For Compound 4, a narrow spectrum of activity was observed over the 280 cell types with moderately potent to strong (GI₅₀=0.68 to 2.92 μM) activity towards 12 cell lines. One strong activity (GI₅₀=0.684 μM) was observed towards A204 (soft tissue sarcoma) similar in magnitude to that observed for Compound 1. Strong activity (GI₅₀=1.23 to 2.92 μM) for Compound 4 was observed towards the following cell lines: 5 lymphoma (Daudi, DOHH-2, GA-10, L-428, ST486); 2 leukemia (MX1, NALM-6); also for T47D (breast), CEM-C1 (leukemia), A-673 (soft tissue sarcoma). The activity towards these cell lines is comparable in magnitude to Compound 1, however, Compound 4 show strong activity towards the J-RT3-T3-5 leukemia cell line (GI₅₀=2.71 μM) approximately 270 times less activity than the very potent activity observed for Compound 1 (GI₅₀=0.0101 μM) towards this cell line.

The plant resin extract showed strong activity (GI₅₀=0.11 to 1.03 μg/mL) towards 24 cell lines: 4 soft tissue sarcoma (A204, HT-1080, RD, SW 872); 4 melanoma (A7, COLO829, Hs695T, RPMI-7951); 3 myeloma (IM-9, RPMI8226, SKO-007); 2 breast (KPL-1, MDA-MB-453); 2 lymphoma (DOHH-2, SU-DHL-5); 2 small cell carcinoma (DMS53, SHP-77); 2 leukemia (Jurkat, NALM-6) and also bladder (UM-UC-3); colon (SW480); thyroid (CGTH-W-1); head and neck (FaDu); and stomach (AGS). For the Hs695T melanoma cell line, calculated on a weight-weight basis, the plant resin extract (GI₅₀=0.11 μg/mL) was approximately 3 times more active than Compound 1 (GI₅₀=0.37 μg/mL) towards this particular cell line. From weight comparison for all other cell lines the plant extract was less active than Compound 1.

Overall, Compound 1 provides a broad spectrum of anticancer activity towards a wide range of cell lines. Compound 2 shows specificity for the LNCaP prostrate cell line, also specific activity towards SK-NEP-1 (kidney), Jurkat, MOLT-3, NALM-6, TF-1 (leukemia) and SKO-007, RPMI8226 (myeloma) similar in magnitude to Compound 1. Compound 4 showed moderately potent to strong activity (GI₅₀=0.68 to 2.92 μM) towards a narrow range of cell lines (12 out of 280) compared with Compound 1 (174 out of 280),

-   -   a) Cryopreserved human PBMC's were drip-thawed.     -   b) Cells were diluted to the appropriate density (1×105 per         well) and seeded into 96-well polypropylene plates with 150 μL         per well of culture medium (RPMI 1640, 10% heat-inactivated FBS,         1% penicillin/streptomycin, 2 mM L-glutamine).     -   c) Cells were incubated at 37° C., 5% CO₂ for 1 hour prior to         the addition of test compounds or controls.     -   d) Test compounds were solubilized in DMSO to make stock         solutions, and then diluted further with cell culture medium.         The positive control, LPS (from S. minnesota R595), was         resuspended in endotoxin-free water at 0.5 mg/mL to make working         stock solutions. Dexamethasone was used as a reference control         compound.     -   e) Compounds and controls, including appropriate vehicle         controls, were added to the PBMC's in volumes of 10 μL and         incubated for 1 hour at 37° C., 5% CO₂. Compounds were tested in         duplicate at final assay concentrations of 10, 3, 1, 0.3, 0.1,         and 0.03 μM. Vehicle control wells simply received 10 μL of the         appropriate vehicle.     -   f) After a 1-hour incubation, 40 μL of diluted working stock LPS         were added to the test compound and control wells to give final         assay volumes of 200 μL. Plates were incubated for 24 hours at         37° C., 5% CO₂.     -   g) Plates were centrifuged at 200×g for 10 minutes. Cell culture         supernatants were collected and stored at −80° C. until needed         for analysis.     -   h) Cytokine levels in each sample were determined using Luminex         methodology, per the manufacturer's protocol.

Results and Discussion

Stimulation of human PBMC's with LPS for 24 hours elicited the measurable release of appropriate cytokines within expected ranges. Conversely, dexamethasone inhibited the LPS-stimulated release of cytokines from human PBMC's, also within expected ranges. Compound 1 elicited measurable inhibition of the LPS-induced release of specific cytokines from human PBMC's, following a 24-hour stimulation.

As seen from the results shown in Table 32, Compound 1 elicited a moderate to strong inhibition of the secretion of all cytokines at the top test concentration, giving measured IC₅₀ values of 4.3 μM, 6.6 μM, 8.8 μM, and 8.9 μM for IL-10, IL-1β, IL-6, and TNFα, respectively. (IC₅₀ values could not be measured for IL-8 and MIP-1α.)

Bioprint Assays

The Bioprint assay (conducted by Eurofins Cerep, France) provides a profile that is designed with the dual purpose of assessing safety at targets with known safety liabilities as well as providing a rich enough profile to search for compounds with similar profiles.

Methodology

Compound 1 was tested at 10 μM. For Compound 1 at 10 μM, the agonist radioligand assays for control specific inhibition of interest for biological activity or safety are as follows:—

GPCR Family:—adenosine A3 (h), 92%; adrenergic alpha 2C (h), 92%; cannabinoid CB2 (h), 71%; cholecystokinin CCK1 (CCKA) (h), 81%; dopamine D1 (h), 67%; dopamine D3 (h), 85%; histamine H1 (h), 64%; melatonin MT1 (ML1A) (h), 91%.

Transporters:—norepinephrine transporter (h), 76%.

Non-steroid Nuclear Receptors:—PPARgamma (h), 91%.

For Compound 1 at 10 μM, the enzyme assays for control specific inhibition of interest for biological activity or safety are as follows:—

AA Metabolism:—COX1 (h), 81%; COX2 (h), 74%.

Compound binding was calculated as a % inhibition of the binding of a radioactively labeled ligand specific for each target. Compound enzyme inhibition effect was calculated as a % inhibition of control enzyme activity. Results showing an inhibition or stimulation higher than 50% are considered to represent significant effects of the test compounds.

Results

Compound 1 results for inhibition of control specific binding to receptors are shown in Table 33 whilst results for inhibition of control specific binding inhibition of enzymes in enzyme and cell-based assays are shown in Table 34.

In Vitro Toxicity: Normal Cell Panel Toxicity Assay

The OncoPanel (Eurofins Panlabs Inc., St Charles, Mo., USA) normal cell proliferation assay measures the proliferation response of normal cells to drug treatments through high-content fluorescence imaging.

Methodology

Normal cells (see description in Table 35) were grown in special medium for each cell type. Cells were seeded into 384-well plates and incubated in a humidified atmosphere of 5% CO₂ at 37° C. Compounds (information in Table 36) were added the day following cell seeding. At the same time, a time zero untreated cell plate was generated. After a 3-day incubation period, cells were fixed and stained to allow fluorescence imaging of nuclei.

DISCUSSION

Compound 1 and reference compounds, paclitaxel, cycloheximide, carbonyl cyanide m-chlorophenylhydrazone (CCCP) and staurosporine, were tested on 4 normal cell types, CCD 841 CoN, HMEC, HREC and Wi38. In summary, Compound 1 showed relatively low toxicity towards all 4 cell lines. Paclitaxel showed low toxicity towards the HMEC cell line and high toxicity towards the other three cell lines. Based on average GI₅₀ for the 4 normal cell lines, the order of toxicity is staurosporine >paclitaxel >cycloheximide >CCCP>Compound 1.

In Vitro Toxicity: ADME-Toxicity Study

ADME-Toxicity study of compounds 1, 2 and 4 was conducted by Eurofins Panlabs Inc, St Charles, Mo., USA using a CYP panel.

Methodology

Cytochrome P450 Inhibition was monitored through HPLC-UV/VIS and HPLC-MS/MS detection. Peak areas corresponding to the metabolite of each substrate were recorded. The percent of control activity was then calculated by comparing the peak area obtained in the presence of the test compound to that obtained in the absence of the test compound. Subsequently, the percent inhibition was calculated by subtracting the percent control activity from 100 for each compound. IC₅₀ values (concentration causing a half-maximal inhibition of control values) were determined by non-linear regression analysis of the concentration-response curve using Hill equation curve fitting [Dierks, E. A. et al. (2001)].

In Vivo Toxicity: Compound 1 Maximum Tolerated Dose for Mice

Two studies were conducted by Eurofins Panlabs Taiwan, Ltd. The purpose of Study 1 was to assess the possible adverse effects of Compound 1 alone or in combination with carboplatin in Maximum Tolerated Dose (MTD) assay. The purpose of Study 2 is a follow-up study performed at escalating doses.

The vehicle information and dosing volume used in the studies are shown in Table 41. Table 42 and Table 43 show results for Study 1 in terms of mortality and body weight observations. In regard to Study 2, Table 44 and Table 45 show results for mortality and body weight observations and behavioral, symptomatic i.e. neurological and autonomic signs for Compound 1, alone and in combination with carboplatin, are shown in Table 46 and Table 47. Corresponding signs for the vehicles are shown in Table 48 and Table 49.

Test Substance and Dosing Pattern

Compound 1 was dissolved in 10% Tween 20/90% PBS or 20% Tween 20/80% PBS for IP injections. Compound 1 was administrated alone or in combination with carboplatin at a dosing volume of 10 or 20 mL/kg for each substance.

Study 1

For mortality, test substance (Compound 1; 100 mg/kg) alone or in combination with carboplatin (8.75, 17.5, or 35 mg/kg; given on the same day) was administered to mice by IP injection to evaluate the possible adverse effects in MTD assay. The mice were a group of 3 female NOD/SCID mice at 6-7 weeks of age. The mortality was observed at 30 min and again at 3, 24, 48 and 72 hours after compound administrations.

For body weight, test substance (Compound 1; 100 mg/kg) alone or in combination with carboplatin (8.75 or 17.5 mg/kg; given on the same day) was administered to a group of 3 female NOD/SCID mice at 6-7 weeks of age. The body weight of each animal was measured and recorded daily for 3 days.

Compound 1 alone did not elicit significant adverse effects and were considered tolerated. All test animals survived over the 72-hour observation period (Table 42). However, Compound 1 in combination with carboplatin was associated with slight to moderate limb tone, and resulted in a 33% mortality after 72 hours of dosing, reflecting the dose level was not well-tolerated (Table 42)

Compound 1, in combination with the lower doses of carboplatin (8.75 and 17.5 mg/kg), was further investigated in the MTD study. Compound 1, injected with two doses of carboplatin on the same day, was associated with slight to moderate abdominal tone during the first 30 minutes of administrations (Table 44 and Table 4S). However, no mortality and body weight losses were observed in test animals over the experimental period, signifying the dose levels were tolerated (Table 44 and Table 4S).

Study 2

A follow-up MTD study was performed to evaluate for the adverse effects of the test substance (Compound 1) at escalating doses alone or in combination with carboplatin (17.5 mg/kg) via IP in a group of 3 female NOD/SCID mice at 6-7 weeks of age.

For mortality, treatment with Compound 1 at escalating doses (200 mg/kg) alone and in combination with carboplatin (17.5 mg/kg; given on the same day) were administered by IP injection to a group of 3 female NOD/SCID mice at 6-7 weeks of age. The mortality was monitored at 30 min and again at 3, 24, 48 and 72 hours after compound administrations.

For body weight, test substance (Compound 1) at escalating doses (200 mg/kg) alone or in combination with carboplatin (17.5 mg/kg; given on the same day) were administered by IP injection to a group of 3 female NOD/SCID mice at 6-7 weeks of age. The body weight of each animal was measured and recorded daily for 3 days.

On treatment with Compound 1 (200 mg/kg) alone and in combination with carboplatin (17.5 mg/kg) exhibited a 33-100% mortality, but no marked weight loss during the study period (Table 30 and Table 31).

Study is designed to continue for 28 days, or until the mean tumor volume within negative control group reaches 2000 mm³, whichever comes first. After TGI is determined, study may be converted to determine Tumor Growth Delay (TGD). Animals are to be sacrificed if/when: 1. Body weight loss >25% 2. Severe tumor ulceration

Estimated Timeline

Animal Arrival: Within one month receiving test compounds

Tumor cells implantation: Within two weeks after animals are obtained

Dosing: Approximately 1-2 weeks after tumor cell implantation

Sample Requirements

Compound 1 150 mg; Gemcitabine 256 mg.

Protocol

Tumor, Xenograft Pancreas, MIA PaCa-2

Procedure: Groups of (8) female nu/nu mice (7-8 weeks old), bred in an animal isolator (IVC racks) under specific pathogens free (SPF) condition at 22 plus or minus 2° C. are used. Viable human pancreatic carcinoma MIA PaCa-2 (ATCC CRL-1420) cells (1.0×107 in 0.2 mL) are injected subcutaneously into the right flank of experimental mice. When tumor volumes reach ˜80-150 mm³ (about 8-10 days post implant), the animals are randomly assigned into groups of eight, and test compounds and/or vehicle dose administrations are initiated (denoted as Day 1). Test compounds are administered as detailed in the “Study Design” section (Table 50). Tumor volumes and body weights are measured and recorded twice weekly over the course of the study period. Animals are monitored as a group. The endpoint of the experiment is a mean tumor volume in the negative control group of 2000 mm³ or 28 days, whichever comes first.

Tumor volume (mm³) is estimated according to the formula for a prolate ellipsoid: length (mm)×[width (mm)]2×0.5. Tumor growth inhibition (% TGI) will be determined twice weekly during the dosing period by the formula: % TGI=(1−[(T−T0)/(C−C0)])×100 where T=mean tumor volume of treated group, T0=mean tumor volume of treated group at study start, C=mean tumor volume of control group and C0=mean tumor volume of control group at study start [Mohammed et al. 1998],

All aspects of this work including housing, experimentation, and animal disposal are performed in general accordance with the “Guide for the Care and Use of Laboratory Animals: Eighth Edition” (2011) in an AAALAC-accredited laboratory animal facility.

Determination of inhibition of CCL2 release from IL-4, IL-13,         IL-22 and IFN-γ-stimulated primary human keratinocytes [assay         number 1280] and determination of the effect on cell viability         [assay number 1243],     -   2. Determination of inhibition of IL-8 release from IL-17A and         TNFα-induced primary human keratinocytes [assay number 1250] and         determination of the effect on cell viability [assay number         1244],     -   3. Determination of inhibition of IL-17A secretion from human         PBMC stimulated with antiCD3/antiCD28-coated beads [assay number         1321] and determination of the effect on cell viability [assay         number 1322],     -   4. Determination of inhibition of IL-4 and IL-2 secretion from         human CD4-positive T-cells stimulated with         antiCD2/antiCD3/antiCD28-coated beads [assay number 1297, 1298]         and determination of the effect on cell viability [assay number         1299],

Disease Relevance Summary

-   -   1. Compounds which inhibit keratinocyte CCL2 secretion may be         expected to have efficacy in atopic dermatitis.     -   2. Compounds which inhibit keratinocyte IL-8 secretion may be         expected to have efficacy in psoriasis.     -   3. Compounds which inhibit IL-17A secretion may be expected to         have efficacy in psoriasis.     -   4. Compounds which inhibit IL-4 secretion may be expected to         have efficacy in atopic dermatitis. Compounds which also inhibit         IL-2 secretion have a broader immunosuppressive effect since         IL-2 is an autocrine growth factor for T-cells.

Inhibition of CCL2 release from IL-4, IL-13, IL-22 and IFN-γ-stimulated primary human keratinocytes LEO Pharma Open Innovation assay number 1280

Disease Relevance

The inflammatory skin disease atopic dermatitis (AD) is characterized by the T-cell cytokines including IL-4, IL-13, IL-22 and IFN-γ. In the present assay, keratinocytes are stimulated with a mixture of these cytokines, and the release of CCL2 (C-C chemokine ligand 2, also called monocyte chemoattractant protein 1 (MCP-1)) is measured in the culture supernatant by proximity homogenous time-resolved fluorescence (HTRF). The purpose of the assay is to measure if test compounds inhibit the levels of CCL2 released by the keratinocytes. Compound which inhibit keratinocyte CCL2 secretion may be expected to have efficacy in atopic dermatitis.

A known steroid, Betamethasone, inhibits CCL2 release in this assay with an EC₅₀ of approximately 15 nM, and an Emax (plateau of the fitted curve) of approximately 60%. A high Emax shows that the compound inhibits a large proportion of the secreted CCL2. A low EC₅₀ value indicates that the compound is potent and to perform the inhibition at low concentrations.

The level of living cells in the wells is measured by the addition of PrestoBlue® and the conversion of Resazurin to Resorufin (fluorescent) in living cells is measured.

% Effect for Viability/Proliferation:

The effect of the test compounds on viability/proliferation is normalized to the PrestoBlue signal in the negative control wells treated with a toxic compound, Terfenadine.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
